The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for Kennebunk Beach over the next couple weeks.
Well, I gotta be straight with you – it’s gonna be a long, flat stretch. There’s really nothin’ worth paddlin’ out for right now. The whole 16-day window is lookin’ pretty bleak. The first recommendation isn’t until Tuesday the 8th of September, and even then, it’s tiny. The water temperature is sittin’ at 65°, which is a touch warmer than normal for this time of year.
We start off on Tuesday morning with a tiny 0.7ft easterly swell, the period is short at 9 seconds, and the combined energy is weak (10). The wind is glassy from the north, so it’s clean, but there’s just no push. That theme sticks around for days. Wednesday the 9th sees a bump up to 3ft in the afternoon, but it’s a messy cross-shore wind and the period drops to a terrible 5 seconds – weak energy (54). Thursday the 10th is blown out with strong W winds at 12 mph on a tiny 2ft to 3ft swell. Not a single day breaks above a 0/10 score in the forecast.
There’s a brief moment on Sunday the 13th where the swell hits 4ft in the afternoon, but it’s cross-onshore, choppy, and the period is a pathetic 4 seconds. The energy is moderate at best (125). That’s the biggest swell of the entire forecast, but with that wind and short period, it’s just messy and lumpy.
The rest of the run is more of the same – tiny heights, poor wind, and no wave energy. There’s a few days toward the third week with clean, glassy mornings (like Friday the 18th to Sunday the 20th) but the swell is 0.7ft or less. Not enough to ride a ripple. The combined energy stays in the teens and twenties.
Absolutely no standouts here. Not a single window where a surfer would even consider suiting up. For this stretch, you’re better off findin’ a good book or a spot to go fishin’. Forecasts can change, but right now it’s a total washout.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
